Application filed SiepteniberA 10, 1927. SerialNo. 218,708.

The present invention vrelates tothe construction of revet-ment-mats of the type disclosed in my prior Fatent 1,166,050, patented December 28, 1915. lt is found that, when 5 using` the revetment-mat shown in the patent, the slope of the bank may change from time to time, and, if this becomestoo steep, the

ballast otn sand or stone which is placed upon shores, and so forth and is constructed of bundles or fascines of brush, twigs, or the f like, which are bound together in a. peculiar manner. ln the invention disclosed in said patent, the transverse cables 1 hold theelels oi' each fascine together and hold the fascines in the form of the mat and acent loops interlocking in a mannerV shown and described in said patent. These 'ascines A are held together' by cables 1, and the whole mat is anchored to a supportQ by means ci cables 3, which are preferably fastened to the transverse cables 1 as indicated.

According to the present invention, there .is applied one or more transverse tascines near the lower edge of the mat. v As indicated in Figure 3, two adjacent loops #i and 5 surround fascines A and are interlocked in the manner shown. The next loop 6 is turned at rightangles to the loops 4 and 5 and passed over the end ot thel transverse fascine B. ln this manner, the ends of the transverse iascines are attached to the mat by the same cables which are used in the :formation of the mat itself. There are also preferably employed additional cables which are suitably tied around thefascines B intermediate their ends, and are then joined to one or more of the transverse cables 1.v ln Athis manner, the transverse fascine is easily` secured, and becomes a per- The i marient part of the revetinent-mat.

ballast 8, such asrock orsand, which is 55 placed ontheouter surface of at least a part ot the revetment-mat, will be held against displacement by the transverse fascine. It

'is apparent that, even if the slope of the bank becomes much steeper than it was at the co beginning, nevertheless the ballast will be retained in its proper position.

lVhile the invention relates specifically to the particular manner oi associsfiting` the vtransw-irse fascine or iascines with the mat 05 proper, nevertheless, 'from a broader point of view, the invention may be embodied in constructions which differ therefrom quite widely. It is vto `be understood, therefore, that the invention vis to be regarded as limited only by the scopeo'f the appended claims.

l' claim as my invention: v

1. A revetment-mat having aplurality of -taseines, cables passing Aaround the fascines tosecure them together, a fascine transverse to and superposed'on the first mentionedl fascines adjacent the lower longitudinal edge of the mat to retain ballast, said cables having loops securing 'the transverse fascine to Vthe first mentioned Vasoines. f 30.

2. A revetment-mat having a plurality of fascines, interlocking cables` passing around the fascines in spaced rows to secure the ascines together, a fascine transverse to and superposed on the irst mentioned fascines 85 Vadjacent the lower longitudinal edge of the mat to retain ballast, one of said cables hav-` ing loops surrounding andsecuring the transverse 'ascine to the i'irst mentioned tascines, and additional vcables extending from one of said iirstV mentioned cables and connected to the transverse fascine. In testimony whereof, I have hereunto j subscribed i my name.
